PDCIDE(4) BSD Kernel Interfaces Manual PDCIDE(4)NAME
pdcide -- Promise IDE disk controllers driver
SYNOPSIS
pdcide* at pci? dev ? function ? flags 0x0000
DESCRIPTION
The pdcide driver supports the Promise Ultra33, Ultra66, Ultra100, Ultra100TX2, Ultra100TX2v2, Ultra133, Ultra133TX2, Ultra133TX2v2, Fast-
trak133 and Serial ATA/150 IDE controllers, and provides the interface with the hardware for the ata(4) driver.
The 0x0002 flag forces the pdcide driver to disable DMA on chipsets for which DMA would normally be enabled. This can be used as a debugging
aid, or to work around problems where the IDE controller is wired up to the system incorrectly.
SEE ALSO ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)BUGS
The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz. This driver may not work
properly on overclocked systems.
The pdcide driver does NOT function correctly on NetBSD/sparc64.
